PvP is a lot slower this week as people are spending all their time grinding out multiple sets of Gree dailies. I personally can't stand them and am queueing anyway, but it's not surprising that new records won't be as common when there's new event content up. I bet once the event ends, the thread pops back up.
I suppose you have a point. Also, just a side note to anyone reading, I looked through all the servers and updated the damage done/death ratio and healing done/death ratio with the highest scores I could find.
